摘要
合成了2个配合物[ZnL2(Him)2](1)和[(Cu2L2(phen)2(μ2-Cl)2).(Cu2(μ2-L)2(phen)2Cl2)](2)(L=4-甲基苯硫乙酸,Him=咪唑,phen=1,10-邻菲咯啉),进行了元素分析、红外、热重等表征,并测定了其晶体结构。配合物1晶体属于单斜晶系,空间群为C2/c。配合物2晶体属于三斜晶系,空间群为P1。配合物1是由N-H…O氢键作用形成的一维带状结构。配合物2的单胞中含有2个分别由氯原子与羧基氧原子桥联的双核独立分子,通过C-H…O,C-H…Cl氢键以及C-H…π作用而构成三维结构。室温固体荧光分析显示配合物1具有较强荧光吸收。
Two complexes [ZnLz(Him)2](1)and [(Cu2L2(phen)2(μ2-Cl)2)·(Cu2(μ2-L)2(phen)2Cl2)](2) (L=4-tolythioacetate, Him=imidazole, phen-1,10-phenanthroline) were synthesized and characterized by single crystal X-ray diffraction, elemental analysis, IR spectra and TGA. The crystal of complex 1 belongs to monoclinic, space group C2/c, with a=3.101 2(6) nm, b=0.578 2(1) nm, c=1.463 8(3) nm,/3=100.962(2)°, V=2.577 0(8) nm^3, Z=4, Mr=563.98, De= 1.454 g·cm^-3, F(000)=1168,μ=1.152 mm^-1, the final R=0.033 2 and wR=0.08 6 for 2 154 observed reflections with I〉2σ(I). The crystal of complex 2 belongs to triclinic, space group P1^-, with a=1.01709(1) nm, b=1.04642(1) nm, c=1.9920 2(3) nm, α=88.649(1)°,β=84.023(1)°, γ=66.699(1)°, V=1.936 25(4) nm^3, Z=1, Mr=1 841.66, Dc= 1.579 g·cm^-3, F (000)=940,μ=1.394 mm^-1, the final R=0.030 7 and wR=0.084 1 for 7 495 observed reflections with I〉2σ (I). 1 shows an undulanting-ribbon structure constructed from N-H…O hydrogen bonds. 2 consist of two dinuclear molecules bridged via chlorine and carboxylate oxygen atoms, respectively. Furthermore, C-H…O, C- H…Cl hydrogen bonding and C-H…π interactions drive 2 to be a 3D architecture. Photoluminescence studies revealed that complex 1 exhibits strong fluorescent emission bands in the solid state at room temperature. CCDC: 690004, 1; 690005, 2.
